Sixty-Six Years of Research on the Clinical Versus Actuarial Prediction of Violence

In their meta-analysis of clinical versus statistical prediction models, Ægisdóttir et al. (this issue) extended previous findings of statistical-method superiority across such variables as clinicians’ experience and familiarity with data. In this reaction, the authors are particularly interested in violence prediction, which yields the greatest support for actuarial models. In the past decade, actuarial prediction has continued to improve, but clinicians have not readily adopted these models, and new models have emerged that encourage reliance on unaided clinical judgment. Psychologists have made progress developing and disseminating actuarial risk assessments and should use the most accurate available measure suited to the task.
